Will.I.Am has a back up plan in case singer Fergie ever decides to leave the group - he will replace her with British pop star Cheryl Cole.

The My Humps hitmakers are currently on hiatus while various members of the group pursue solo projects, but plan on getting back together for future albums and tours.

But will.i.am recently collaborated with Cole on his new single Heartbreaker and he insists that if Fergie decides not to rejoin them, Cole would be first in line to take her place.

He says: "If we didn't (have) Fergie, she (Cole) would be in the Peas - that's how cool she is."

The rapper is also partial to Cheryl's humps.
